Pilots reveal safety fears over Boeing’s fleet of Dreamliners

Airline pilots have voiced fears over the safety of a fleet of Boeing aircraft after a crucial fire-fighting system has been found to have the potential to malfunction. Boeing has issued an alert to airlines using its flagship B787 Dreamliner, warning that the switch used to extinguish an engine fire has failed in a “small number” of instances. The switch also severs the fuel supply and the hydraulic fluid to prevent flames spreading. UK airlines Tui, British Airways and Virgin Atlantic operate more than 60 Dreamliners between them. The US regulator, the FAA, has decided not to ground the fleet, despite admitting a “risk to the flying public”. Pilots, however, claim that the safety of passengers and crew is being compromised. “If there was an engine fire on a transatlantic flight and the aircraft had one of the defective fire switches, then we would have to fly with a burning wing for up to three hours before we could safely land,” a pilot with a British airline said. In its alert to airlines, Boeing warns that long-term heating can cause the fire switch to stick in the locked position so it can’t be used to release the two fire extinguishers in each engine. The FAA has issued an airworthiness directive, mandatory instructions to air operators, announcing that the problem is “likely to exist or develop in other products of the same design” and that “the potential exists for an airline fire to be uncontrollable”. However, it stopped short of grounding the aircraft and instead ordered airlines to check the switch every 30 days.<br/>
